以总潜在沉淀物为指标,考察了沥青质分散剂对船用燃料油沥青质分散性的影响,并对其分散机理进行了讨论,结果表明,十二烷基苯磺酸、十二烷基苯酚、十二烷基醇和十二烷基胺均对燃料油中的沥青质有一定的分散作用,其中,十二烷基苯磺酸分散性能最好,99%以上的以总潜在沉淀物形式检测到的沥青质可以被其重新分散到燃料油中,其良好的分散性可能与十二烷基苯磺酸分子中的酸性官能团和苯环有关。  相似文献

Normal phase preparative and semi-preparative liquid chromatography were used to isolate fractions of varying polarity from corn, soybean and sunflowerseed oils. Reported here is the composition of one fraction, less polar than triglycerides, determined by isolating the individual ?peaks? of a semi-preparative separation using as starting material the mix of compounds obtained from a large scale separation. These peaks were then analyzed by high performance liquid chromatography (LC) gas chromatography (GC), mass-spectrometry (MS) with and without GC, in both electron impact (EI) and chemical ionization (CI) modes, and carbon-13 nuclear magnetic resonance (NMR) spectroscopy. Semi-quantitative data were obtained for many of the components found in these semi-preparative isolates including hydrocarbons, steryl esters, triterpenyl esters, phytyl esters and geranylgeranyl esters. The weight percent and composition of the preparative fraction differed substantially among the three oils. Corn oil had the greatest amount, at 1.25% of the starting oil, and was composed mostly of steryl and triterpenyl esters. Sunflowerseed oil, at 0.7%, and soybean oil, at 0.3%, showed greater variety in that branched chain esters were included with the steryl/triterpenyl distributions.  相似文献

Recycle of heavy oil (>340 °C) to the retort, in order to crack/coke the oil to lighter fractions, was investigated as a means of producing shale oil of more desirable product slates. Conversion of heavy oil to light oil (<340 °C) by thermal cracking and coking in the absence of and during oil shale retorting was studied using the CSIRO BIRCOS retort. As expected, the conversion by thermal cracking increased as temperature increased, with most of the net oil loss in the form of gas. By contrast, the conversion by coking alone decreased as temperature increased, with coke representing all the net oil loss. Thermal cracking was found not to be a first-order reaction, by showing a reduced conversion of heavy oil with reduced concentration of oil vapour. Retorting Stuart oil shale with heavy oil feeding and simultaneous cracking and coking showed a conversion of 19.1 g per 100 g feed heavy oil to 10.9 g light oil, 2.2 g gas and 6.0 g coke, with a net oil loss of 3.8 g per 100 g shale oil produced. These data were used to generate a set of parameters for a mathematical model which simulated a heavy oil recycle loop.  相似文献

World-wide use of sunflower oil is second only to soybean oil. Interest in domestic use as a premium salad oil is very recent. The high ratio of polyunsaturated-to-saturated fatty acids makes sunflower oil a premium salad oil. Sunflower oil, however, contains a small amount of high melting wax which must be removed to avoid settling problems. It is possible to produce a brilliant, dewaxed, deodorized sunflower oil with over a 100-hr cold test at 0 C. This quality oil can be produced by conventional caustic refining, dewaxing, bleaching and deodorization. A quality finished oil may also be produced by dewaxing and steam refining. This paper reviews various methods for processing sunflower oil from the crude state through the finished, dewaxed, deodorized salad oil.

Conclusions Data obtained on the solubility of hydrogenated peanut oil in refined peanut oil and the behavior of the mixtures on cooling indicate that freedom from oil separation on storage is largely determined by the nature as well as the amount of solid crystals present in the oil. The results suggest that the best procedure for prevention of oil separation would involve shockchilling the molten mixture to produce the finely divided metastable crystalline modification followed by tempering at such a temperature as to permit transformation of the crystals into the more desirable higher-melting form without changing the finely divided state necessary for improved palatability. The data imply that under controlled conditions any amount of the high-melting modification of the hard fat incorporated in peanut oil above the solubility temperature in excess of 2% should produce a mixture free from oil separation under average storage conditions. The choice of the actual concentration of the hard fat, above the minimum amount, would depend upon the degree of plasticity desired. Ambient temperature to which the mixture is likely to be subjected will influence to a considerable extent the selection of the hard fat content. The information obtained is of fundamental importance in connection with the problem of oil separation in peanut butter.

原油在线调和调度对于优化炼油计划和保障先进控制的实施具有重要的意义。此问题复杂度高,需要研究更加高效的求解算法。实际生产过程中,既存在主炼原油和若干种掺炼原油混合炼制的情况,又存在无主炼原油的情况。无主炼原油的情况,油品配对和掺炼比紧密关联,难以直接描述。本文针对无主炼原油的原油调和调度问题提出了一种新颖的描述方式,并给出模型的构造算法,进一步针对其两层结构利用基于序的方案进行了求解,对实际原油性质数据的仿真结果表明,基于序的求解算法可以大幅度提高计算效率。  相似文献

Preparation of laurel oil alkanolamide from laurel oil   总被引:1,自引:1,他引:1  
A low-temperature synthesis of laurel oil alkanolamides directly from laurel oil and ethanolamine was carried out in essentially quantitative yields. The ethanolamine/laurel oil molar ratio used was 10∶1. Even though amine served as a catalyst in the reaction, we used sodium methoxide at a ratio of 0.2–2% as a second catalyst. The reaction was complete in 1–9 h at room temperature. The identity of the amide was confirmed by IR and 13C NMR spectroscopy.  相似文献
